To all 'whom t may concern? Be it known that we, Hanni S. Jnwnm. and Fnnnnnrcn C. Jnwnnn, citizens of the United States, residing at Chicago, in the county of @ook and State of illinois, have invented new and useful improvements in titi Printing Apparatus, of which the following is a specification.

This invention relates to apparatus for printing` naines, advertising matter, etc., on

' paper strips used for sealing packages and undles, and its object is to provide a printing apparatus of this kind embodying certain novel and improved features of construction., and modes of operation as will appear in the detailed description hereinafter.

lin order that the invention may be better understood, reference is had to the accompariying drawings, forming a part of this f specification, wherein Figure 1.is a central vertical section of the apparatus; Figs. 2, 3 and 4 are sectional views on corresponding lines in Fig. 1, and Fig. 5 is a sectional detail showing a modified roll holder structure.

Referring specifically to the drawings, 10 denotes a paper roll, the same being composed of a strip which is gurnmed on one side so that it may be used Vfor sealing packages, etc., the other side being adapted to receive an impression from a printing roller 11 located above the roll in rolling contact therewith. Above the printing roller are two inking rollers 12 and 13, which are in contact with each other, the lower roller being in contact with the printing roller. The several rollers are in vertical alinement, and their axes are paralled.

'lihe paper ro-ll 10 is on a wooden core 1A containing a steel bushing 14, through which latter passes a shaft 15, which may be a bolt having a head 15a on one end, and threaded at the opposite end to receive a wing nut 15b. The bushed core is loose on the shaft 15 and turns freely thereon. rlFhe rollers 11, 12 and 13 are mounted on shafts 11a, 12a and 13, respectively.

rllhe hereinbefore described assembly of rollers is enclosed in a casing consisting of upper and lower sections which are hingedly connected, as shown at 16 so that the upper section may be swung rearwardly and downwardly away from the lower section, as shown dotted in Fig. 1, to leave the roll 10 eaposed.

The lower'casing section consists of a base plate 17, side walls 18 and a rear Wall 19, the section being open in front for exit of the printed paper strip. rll`he side walls and the rear Wall are integral and they are secured to the base plate by brace bars 20. lin the top edge of the side walls are downwardly extending vertical slots 21 in which the ends of the shaft 15 seat. At the ends of the paper roll 10 are guard plates 22 having apertured central bosses 22 through which the shaft 15 passes, said plates being located between the side walls 18 of the lower casing section and the ends of the paper roll.

he upper casing section is composed of a front wall 23, a rear wall 21, side Walls 25 and a top 26, the latter being hinged to the rear wall, as shown at 26a, and being held closed by a suitable spring latch 27 carried by the front wall. lin the side walls 25, on the inside, are vertical grooves 28 whlch are closed at the top by the hinged top 26, and in which grooves the ends of the roller shafts 11a, 12a and 13a slidably seat. The rollers 11, 12 and 13 therefore automatically descend as the diameter of the roll 10 decreases, and the printing roller 11 is kept in working contact with the roll, without the use of springs or other presser devices, yand at the same time the contact between the rollers is constantly maintained. When the paper roll requires replenishing, the upper casing section is swung open as shown dotted in Fig. 1, which leaves the slots 21 vopen at the top for removal of the shaft 15 and the core la. When the apparatus is ready for operation, the upper casing section closes the slots 21.

As shown in Fig. 3, the upper casing section may be a sheet metal stamping made in two parts, the joints being at the front and rear and covered on the inside by securing strips 29. The lower casing section can also be -a sheet metal stamping.

lin front of the paper exit end of the lower casing section is located a water tank 30 in which is mounted a moistening roller 31 across `which the gummed side of the printed strip is adapted to be drawn. 'ihe sides of the tank are vertically grooved, as shown at 32, and in said grooves seat slidably the ends of the shaft 31'a of the roller 31. rlihe bottom of the tank has a downwardly directed central boss 33 which seats in an aperture 3a in an extension 35 of the ica base plate 17. rlFhe parts-35 and 17 are fastened together by a strip 35a. The tank 30 may also be a sheetmetal stamping.

t the open or strip-exit end of the lower casing section is a blotting roller 36 under which the printed strip passes, and against which it is pressed by a flat spring 37.

The apparatus is also provided with a means for cutting off the desired length of printed strip. The cutter is a blade 38 having a serrated cutting edge and located at the open or strip-exit end of the lower casing section, and extending transversely therebf above the blotting roller 36. The strip is severed by being carried upwardly and pressed against the blade 38.

The blade 38 is carried by a cross bar 39 extending between and secured to the side walls 18 of the lower casing section. This cross bar also carries a spring .latch 40 for holding the upper casing section down in closed position, as shown in full lines in Fig. l. The forward ends of the guard plat-es 22 rest on the cross bar 39,'whereby they are prevented from turning on the shaft 15.

Fig. 5 shows an expedient for supporting a very narrow paper strip on the core 14.

Such a strip leaves the guard plates 22 spaced'from the casing sides 18, and hence spacer sleeves 41 are interposed between said plates and casing sides, said sleeves being mounted'on the shaft 15.

We claim: 1. -The combination of a casing composed of upper and lower sections, the upper secf tion being hinged to the lower section and having vertical grooves in its side walls on the inside thereof, and the side walls of the lower section having vertical slots in their top edges, a paper-roll supporting-shaft removably mounted in the aforesaid slots, and contacting inking and printing rollers hav ing shafts which are mounted in the aforesaid ooves and free to slide therein.

2. he combination of a casing composed of upper and lower sections, the u'pper section being hin ed to the lower section and having vertica grooves in its side walls on the inside thereof, and the side walls of the lower section having vertical slots in their top edges, a paper-roll supporting-shaft removably mounted in the aforesaid slots, and

contacting inking and printing rollers having shafts which. are mounted in the aforesaid grooves and free to slide therein, the upper` casing section having a hinged top which 'closes the upper ends of the grooves.

3. The combination of a casing composed of upper and lower sections, the upper section having vertical grooves in its side walls on the inside thereof, and provided with a hinged top closing the upper ends of tho grooves, contacting inking and printing rollers mounted in the aforesaid grooves and free to slide therein, and paper-roll supporting-means in the lower casing section.

4. The combination of a casing composed of upper and lower sections, the upper section having vertical rooves in its side walls on the inside thereo contacting inking and printing rollers mounted in the aforesaid l grooves and free to slide therein, and paperroll supporting-means in the lower casing section.

In testimony whereof we aix our signatures.
